I. Interface cable of MIM-1E1/MIM-2E1 and MIM-1E1-F/MIM-2E1-F modules
MIM-1E1/MIM-2E1 and MIM-1E1-F/MIM-2E1-F interface cables are G.703-compliant
cables (referred to as E1 cables throughout the rest part of the manual). E1 cables are
divided into two types: 75-ohm unbalanced coaxial cables and 120-ohm balanced
twisted pair cables.
